Body weight or about 2% of calcium. The human body has 99% of the calcium in the bones and teeth with these places but also calcium storage room. When insufficient calcium is easily lead to insomnia, cramps, irritability and decreased bone density, when the body needs less than 1% of calcium, the body will be made of calcium from the bones to maintain a sufficient amount of calcium in the blood, so if the long-term calcium insufficient, we must always remove calcium from the bone, resulting in easy fatal osteoporosis.
Calcium absorption is better body calcium citrate, calcium lactate followed, calcium gluconate, calcium carbonate and finally. Not only the body's absorption of calcium citrate, calcium carbonate better than traditional in fasting, even after a meal is also better than calcium carbonate.
Calcium citrate utilization of the living body, which is 2.5 times that of traditional calcium carbonate. And calcium carbonate will take about a third of those who have bloating or constipation circumstances, but by itself is relatively poor gastrointestinal absorption, may also increase the chance of urinary tract stones, while calcium citrate is rare these side effects. The more readily decomposed in the gastric acid compound is calcium citrate, calcium gluconate, calcium malate. It is taken from that kind of informality in the source (but must be non-polluting Conditions However, every time the content of the highest calcium intake is 200mg (calcium in gastric acid ionizable limit
Elderly long-term calcium drug selection should be careful. Currently, prevention and treatment of osteoporosis in the elderly because while taking calcium supplements is very common, foreign scholars have recently noted that calcium citrate may cause intestinal "aluminum" increased absorption of aluminum have central nervous system toxicity, senile dementia brain often accumulated abnormal amount of aluminum. So long-term use calcium compound, calcium should choose the ideal, not to choose a single bioavailability of calcium citrate.
